<div style="color:black;font: 12pt Arial, Helvetica, sans-serif;">Every golf cart on planet earth uses Anderson connectors from battery bank to vehicle. Anderson Power Products. They have a good web page. The connectors come in several sizes, so you can use the larger for 36 volt and smaller for 12. No way to mix them up, then. I have them for my pods to connect my fuses between the bulkhead and the battery banks.

<div dir="ltr">What about securing the battery lugs to the copper allthreads with jam hex nuts instead of regular hex nuts and then trim the all treads off a bit with an angle grinder. This should save about the thickness of one the hex nuts. From your drawing, I don't know how much of clearance issue you have. If it is small on the order of 1/4" or so, this might work.</div>

<div dir="ltr">Here's a drawing as I don't think I could get a real photo that was better. The only option that I can think of if it would work, short of finding a battery that was say a 1/2" shorter in height, would be to not use the aluminum trays and if the battery's are narrow enough to fit between the horizontal legs of the SS angle, I could just have them sit on the inner wall of the pod which might solve my problem but then I have the problem of friction sliding them in but more of a problem pulling them back out when needed.
<div>I guess I could cut a piece of aluminum plate the width of the batteries that is the full length of the pod and then maybe install a set of small rollers on the far end so when I reach in and lift the front end, which would be very hard due to the weight of the 4 batteries, and start pulling them all out, the back rollers would lessen the friction? I was planning on going with the AGM batteries anyway so maybe I can find one that is a little shorter so I can use my battery tray? I'll start calling some battery companies to see if I can get one that is a little shorter.

<div dir="ltr">Well I just got blindsided by my first, what I would call major problem, since I started this project which I guess is pretty good but it might be a major one. On any project, you tend to look forward the best you can when you fabricate something to make sure you are not painting yourself into a corner but this one may have got me I think.
<div><br clear="none">
<div>My battery pod design is a little different than what's on the plans. I attach the end caps a little differently but I also take the power into the sub a little differently as well. I wanted to be able to remove the batteries when needed without a lot of trouble though the end caps will usually always stay on. I built an aluminum tray for each side that all 4 batteries fit into end to end and that tray slides along two pieces of SS angle welded into the inside. One leg goes up and the other leg points inward at each other.</div>
<div> </div>
<div>After building the aluminum trays using 1/4" flat bar, I snuggled the SS angle to both sides of the tray adding a little slop to it so they wouldn't be too snug and bind then put them inside the pipe and went down until the SS angles touched the inside of the pipe and tack welded the SS angles in place plumb and true. Before doing all this, I made a plywood template of it to confirm that I would have the clearance I needed based on using the 12 volt wet cell battery the plans call for.</div>
<div><br clear="none"></div>
<div>Even with the thickness of the SS tracks and aluminum trays, I had a comfortable clearance for passing my sealing ring. Well,,,I found out that with the batteries in the tray, they will not slide under/past the copper all thread that comes in at the 32 degree angle from the hull and I cut those about as short as I could to be able to get the 2 nuts on them with a lug. From what little I understand about wet cell batteries, I guess they come in different classes based on certain things so I don't think I can just go get ones that are a little shorter. I am all ears guys! I have had usually non P subbers ask me why I didn't use new state of the art lithium batteries or golf cart batteries but I am limited on space and dimensions and also a lot of thought went into trimming the boat out using that particular battery. </div>
